Raspberry Pi 4 vs Pi 3 – What are the differences
the Raspberry Pi 4 model B has just been launched, it may be worth checking out the differences against the previous latest single board computer from the Raspberry Pi foundation, namely Raspberry Pi 3 model B+.

The Raspberry Pi Foundation has done a pretty amazing job here with adding the extra performance (CPU up to three times faster), and plenty of new features (4K, GbE, USB 3.0..) while keeping the same price tag for the board with 1GB RAM. Some of the features I don’t see advertised and are present on some of the competing boards include HDR (High Dynamic Range) and VP9 video decoding.
